Several years old SketchUp project, revisited with SU PRO 2014 and rendered with LightUp 2014.
"Bling-bling" duplex atrium house over garage/entry level: glass roofs (some curved), glass bridges and balustrades, mirrors, spots, sculptures… more on the LOFTRIUM concept on http://www.loftrium.com).

I use "stroke" depending on my needs to outline some details: it was not the case in this post.
On the contrary, the "Glazed Atrium Houses (4)" was more sketchy, so there I used the "stroke" option abundantly.
Other posts are a mix of both choices: great LightUp feature, by the way!

None of the pictures shown are altered/edited, (other than Photoshop bundle size reduction).
